142// ===============================================
143//
144// The event display can ve invoked by executing the macro "display.C"
145// A canvas like in the picture below will appear.
146//
147// On the left side of the canvas, the following buttons appear:
148// *Next* to move to the next event
149// *Previous* to move to the previous event
150
151// *Pick* Select this option to be able to point on a track with the
152// mouse. Once on the track, use the right button to select
153// an action. For example, select SetMarkerAttributes to
154// change the marker type/color/size for the track.
155// *Zoom* Select this option (default) if you want to zoom.
156// To zoom, simply select the selected area with the left button.
157// *UnZoom* To revert to the previous picture size.
158//
159// slider R On the left side, the vertical slider can be used to
160// set the default picture size.
161//
162// When you are in Zoom mode, you can click on the black part of the canvas
163// to select special options with the right mouse button.
164
165//
166// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
167// When you are on a track, select the menu item "InspectParticle"
168// to display the current particle attributes.
169//
170// You can activate the Root browser by selecting the Inspect menu
171// in the canvas tool bar menu. Then select "Start Browser"
172// This will open a new canvas with the browser. At this point, you may want
173// to display some histograms (from the Trees). Go to the "File" menu
174// of the browser and click on "New canvas".
175// In the browser, click on item "ROOT files" in the left pane.
176// Click on galice.root.
177// Click on TH
178// Click on TPC for example
179// Click on any variable (eg TPC.fX) to histogram the variable.
180//
181// If you are lost, you can click on HELP in any Root canvas or browser.
